PERCOLATOR.

- Tall whom t may concern:

Be it known that I, ISRAEL GEFTER, a subject of the Czar of Russia, and a. resident of Meriden, in the county of Newv Haven and State of Connecticut, have invented a new and, Improved Percolator, ofwhi'ch the following is a specification.

My invention relates to the class of devices used inthe prepa-rationl of beverages, more especially coffee, andi the object of my invention among others is. to provide a device of this classV that shall be extremely eiicient and rapid in-k operation.

@ne form ofdevice embodying-my invention, andv inV the use of which. the object above mentioned may be attained', aswell as others which. will appear from theI following: description, is illustrated in the accompanying drawings, inv which- Y Figure l is a View inside elevation of an urn embodying my invention with. partsV broken away to show construction. Fig. 2 is a view iny cross section on plane denoted by dotted line 2 2 of Fig. 1. Fig. Sis-a detail View in cross section on plane denoted by dotted line 3 3 of Fig. 1. Fig. 4: is a detail side view of the fountain.

Wrhile my inventionv may be embodied in differentforms of devices for preparing beverages, as it finds readyy adaptation in an urn employedV for suoli purpose, I' have selected such for the purpose of illustration and description of my invention herein.

In the accompanying drawings the numeral 5 denotes the body of the urnv having a rest 6- at its lower end serving as a; means of support, a spout 7 through which thecontents of the vessel may be drawn, a basket 8 inserted in the upper part ofthe body, this basket being perforated. at the bottom and within which the coffee or like material is placed, anda cover 9 closing the mouth of thebasket A diuser 1'0 also havinga perforated bottoinmayv be located within the basket 8, if desired. All of the parts above described are of old and well-known, construction, and further descriptionL is therefore deemed unnecessary herein. The botptom of the pot is reduced inv size forming a depression l1, preferably tapering from a larger dimension at the top to a smaller dimension at the bottom, this depression extending within the flange or rest 6. An opening' l2 is formed through the bottom of the depression and a threadedl nipplel 13 is. inserted through this opening, and' upon Specification of Letters Patent.`

Patentedct. 28 1913.

the threadedend of which a heating plate 145 is.V secured rllhis nipple has a iiange or flanged head; l5. resting upon the bottom of the depression. ll and formingv1 a; riloof collsider-ablethickness and of less size iin, diam? eterthan; the bottom. of the depressionA for the. purpose of forming a circulating Cham.h berl6=. The flange 1,5, hasradal openings lf2, and the central' opening'- through; thev nipple forms, in connection with1 a recess 1.8 in. the heatingy pla-te, a heating chamber 19 in said plate.

A fountain 20, is formed to; fit within the depression l1", the construction. being such that the bottom, ofthe fountainV rests upon the flange of the nipple 13 and at the same, timeV the fountain completely fillsv the depression fromthe head' of the nipple to the top of the depressi-on*y so. that. no liquid can enter around the fount-ain. This fountain is preferably formed of thin metal With an. interior chamber 2l, andi circulating plate 22 is secured to the bottom of the fountain. Thiscirculating platey in fact constitutes a part of the fountain, and? it is removablysecured in place, in the preferred form@ of' constructionl a flange 23v extending from. the upper surface of the plate` at its periphery, and of a size indiameter to` re.- ceive the other part of the. fountain,` being provided: with angular slots 28 to receive pin-s projecting from the side of the fountain. A passage 24A of spiral form extends through the fountain, as clearly shown in Fig. 21,'in' thepreferred form of construction Y and; as. shown; herein, this: passage being located; between the-platef22- and the bottom ofthe other party of the fountain: and preferably inr the plate itself, in which instance the. otherpart. of the fountain forms one wall: of the passage. l

An inlet passage 251 is formedl within a sleeve 261 surrounding a fountain tube 27', which tube is secu-red to or forms a; part of the plate 22, and has a passage extend?- ing from thevheating chamber 19 to deliver the fiuidl contents intoy the baskets 8 and 10. Ports 29 are formed through the wall ofthe sleeve 26 by means offwhich the liquid contents. of' the vessel 5'. enter the inlet pas- 25'` and areA conducted to the spirally extending passage 24. Aifter passing several times in a circular pathtothe periphery of the plate 22'the-liquid' passes through a port SOiint-o the circulating. chamber 16, through the radial openings. 172V inf-ze the heating chamber 19 in which it is quickly heated to an extent to cause it to be forced upward through the fountain tube 27. It will thus be noted that the liquid contents of the vessel are located at a considerable distance from the heating chamber 19, so that said contents do not become unduly heated, and in passing from the interior of the vessel to the heating chamber 19 they are constantly subjected to the action of the hotter fluid which is passing up through the fountain tube or which is located in the heating chamber 19. The

passage is so devious that the force of the structed in exact accordance with that shown and described herein.
